SIGNAL LAMP OR LANTERN GLASS HOLDER.

Specification of Letters Patent.

Patented Dec. 24, 1907.

To all whom it may concern:

Be it known that I, WILLIAM S. HAMM, a citizen of the United States, and resident of Lakeside, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Signal Lamp or Lan tern Glass Holders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

My invention relates to holders for colored glass plates, used in connection with signallamps of that type in which a frame, carrying a plate of colored glass, is movable into and out of register with the lens of the lamp.

The object of the invention is to provide means for removably securing a glass plate within the frame; and it consists, broadly, in

the combination with a suitable frame forreceiving the plate and a detent for engaging the latter at one of its'edges, of a pivoted plate carried by the frame and adapted to swing over the glass plate and secure 1t to its seat.

It consists, further, in the provision of means for controlling the pivoted plate and of supplemental means for raising the glass plate from its seat as the securing plate is disengaged from it.

The invention is illustrated in the accompanying drawings, in which- Fi ure 1 is a face view of the frame provided with a plate of glass and embodying one form of securing device; Fig. 2 is a sec 35 tional view on the line 22 of Fig. 1 Fig. 3

is a detail face view of the frame, showing a. modified form of construction Fig. 4 isa seotional detail on the. line 44 of Fig. 3; Fig. 5 is a view similar to Fig. 3, showing a further modification; and Fig. 6 is a detail section on the line 66 of Fig. 5.

The frame or, as it is sometimes called in the art, the frame-arm for carrying the glass is substantially pear-shape, comprising an apertured body portion 10, within which the glass plate 11 is seated, and a stem 12 which serves as the means of attachment of the frame to the lantern with which it is to be used. The frame is preferably, though not necessarily, of sheet metal. As shown, its stem is reinforced by means of a plate 13, carrying an apertured hub or sleeve 14, the

. axis of which is perpendicular to the plane of the frame and which serves as means for pivotally attaching the frame to the lamp.

The body 10 of the frame has a marginal upstanding or angular flange 15, which may be continuous, its function being to prevent lateral play ofthe glass plate 11. A lug or finger 16 projects inwardly from the upper edge of the flange 15, and may be integral therewith. This lug serves to hold the plate 11 to its seat at its outer edge. An oscillat'able finger or plate 17 is pivoted at 18 to the frame at its base or stem side, and is of such length that its free end 19 will extend over the plate 1 1. When, as in the construction shown, the portion of the frame to which the plate 17 is pivotally secured is of less thickness than the glass 11, the plate is offset, as shown at 20, to bring its outer end to the proper plane.

In the form of construction shown in Figs. 3 and 4, the plate 17 is provided adjacent its outer end with an upstanding flange 21, which serves as a convenient means for applying pressure. In this form of construction the plate 17is also provided with an arm 22, extending from its pivoted end at a slight angle from its body portion, the outer end of this arm being offset downwardly, as indicated at 23, to bring it to the surface of the body portion 10, the function of this arm being to pass under the glass plate 11 as the securing plate is moved out of engagement therewith, thereby raising the glass from its seat and facilitating its removal from the frame.

In order to lock the securing plate 17 against accidental displacement, a boss 17 may be formed in its under surface for frictionally engaging a complementary recess 13 formed in the upper face of the plate 13.

In the modification illustrated in Figs. 5 and eye securing plate 24 is shown which is more nearly circular in form and slotted radially, as shown at 25, and so bent that one of the lips, as 26, formed by the slot will ride over and the other, 27, will pass under the plate 11. In this preferred construction the inclination of the two plates is such that they act upon the glass as cams, the one for forcing it to its seat and the other for forcing it therefrom. The body 10 is depressed, as shown at 28, to form a recess for receiving the lower lip 27 of the plate 24, and a boss 29 is struck up from the bottom of this recess for frictionally engaging this lip and thus locking the plate 24 against accidental movement. In this form of construction the plate 24 is provided with a laterally projecting arm 30, which extends beyond the body tatin the operation of securing or removing the g ass. The outer end of the arm 30 is also provided with a downwardlyturned flange 32, which serves as a stop .by engaging the edge of the body 10.

The stem 12 of the frame and the plate 13 may be secured together in any desired manner. As illustrated in Fig. 3, such securing means consists of rivets 33. In the construction of Fig. 5, the two parts are secured together by means of lugs 34, 35, formed on the member 12 and folded over the plate 13.

I claim as my invention.

1. In a signal-lamp or lantern, "an apertured frame-arm for a color-glass having an angular rim extending around the major portion of the periphery of the glass, a finger overturned from the rim at one side and a pivoted plate at the opposite side with an offset free end to pass over the edge of the glass.

2. In a signal-lamp or lantern, an apertured frame-arm for a color-glass having an angular rim extending around the major portion of the periphery of the glass, a finger overturned from the rim at one side, a pivoted plate at the opposite side with an offset free end to pass over the edge of the glass, and means for holding the said pivoted plate in place free from accidental displacement by vibration.

3. In a signal-lamp or lantern, an apertured frame-arm for. a color-glass having an angular rim extending around the major portion of the periphery of the glass, a finger overturned from the rim at one side, a pivoted plate at the opposite side with an offset free end to pass over the edge of the glass, the frame-arm being provided with a recess and the pivoted plate with an interlocking projection for holding said pivoted plate in an initial position of use free from accidental displacement by vibration.

4. In a signal-lamp or lantern, an apertured frame-arm, composed of an apertured sheet metal part and a plate connected thereto by rivets, a rim formed on the sheetmetal part bounding the major portion of the aperture therein and into which rim the color-glass is adapted to be received and fit,
